This is the safety alert symbol used for the OPERATING INSTRUCTIONS section of this manual to alert you to potential personal
injury hazards. Obey all instructions to avoid possible injury and/or property damage.
MODEL 791-5222 CAR DOLLY
1. Make sure the vehicle is on a hard, flat, dry surface and the transmission is in PARK or engaged in a gear if a manual transmission before
using the dollies.
2. Open the release valve knob by turning it two complete revolutions in a counterclockwise direction. Pull the roller arms far enough apart
where they will straddle the vehicle’s tire.
3. Push the dolly in toward the tire where the roller arms are straddling the tire and the center of the tire seems to be in line with the center
of each roller arm.
4. Turn the release valve knob in a clockwise direction until tight. Activate the foot pedal so the roller arms start approaching the tire and
check to see the dolly roller arms are properly aligned with the tire.
5. Continue to activate the foot pedal until the tire is lifted at least 1” off the ground.
6. Repeat steps 1 through 5 on the remaining three tires.
7. Once the vehicle is supported by the dollies, move the vehicle slowly and carefully.
8. Lowering a tire to the ground can be achieved by slowly and carefully turning the release valve knob in a counterclockwise direction.
Making sure the dolly’s lift arms are not applying pressure on the tire, the dolly can then be pulled away from the tire. The remaining three
tires can be lowered following this same procedure.

2. Make sure the foot pedal is depressed and secured with the hook latch.
3. The previous steps must be completed before installing the dolly on the rack.

installed as shown in the picture on page 1.
5. The loaded rack can be moved by pushing or pulling on the hydraulic pump ends of any of the dollies slowly and carefully. Keep feet clear
of rack and swivel caster wheels.
